all clear signal
Danger has passed
An all clear signal indicates that danger has passed and normal activity can resume.
Originally from air raid sirens announcing the end of a bombing threat, now used broadly for any situation where a hazard or obstacle has been removed: We got the all clear signal from the doctor.
Often shortened to just the all clear.
